A young woman is at her doctor's appointment when the doctor says, "Ma'am, I've got your results, and it appears that you are pregnant."

The woman appears shocked. "What!? You've got to be..." She pauses for a moment. "...Kid-in-me."

After a a few moments of her giggling turn into silence, the doctor replies "Did you seriously get pregnant just to say that joke?"

The woman says "It was totally birth it."
